PTFE latches hold the aerogel layer under tension before it is released. The latches are created out of PTFE (teflon) to minimize the friction between it and the aerogel.
A polymer shield covers the wiring for the motors, piezoelectric sensors, and important electrical components.
Three ultra small DC Sanyo stepper motors actuate the latches, releasing the aerogel. Only 4.7mm in diameter, these micro motors are able to fit between the aerogel and the CubeSat's frame.
A transparent, ultra light silica aerogel layer slowly decelerates the incoming micro-debris.
Two 3 millimeter springs apply a constant tension force to the aerogel. When the latches are released, the springs launch the aerogel forward.
SafeSat frames are held together with M2.5 screws, enabling straightforward assembly and maintenance.
The SafeSat is attatched to the CubeSat using an aluminum mounting bracket. This bracket comes in different sizes/configurations, allowing users to attatch SafeSat on any type of solar panel.
